www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-13211-3E General Purpose Linear IC’s General Purpose Converters CMOS D/A Converter for Digital Tuning (With Built-in OP Amp and I/O Expander) MB88141 s DESCRIPTION The FUJITSU MB88141 is a D/A converter with 12 built-in channels. The 12 analog output channels have built-in OP Amps, providing large current drive capability. Data input is compatible with I2C specifications, and is controlled by two control lines. The built-in I/O expander function allows the MB88141 to be controlled by devices incompatible with I2C bus specifications (provides conversion between I2C serial and 8- or 4-bit parallel I/O). Can be adapted for tuning by electronically variable or pre-fixed resistance, etc. s FEATURES Ultra-low power consumption (0.9 mW/channel Typ.) Ultra-compact package Built-in 12-channel R-2R type 8-bit D/A converter Built-in analog output amplifier (maximum sink current 1.0 mA, maximum source current 1.0 mA) Analog output range 0 V to VCC (Continued) s PACKAGES 24-pin plastic DIP 24-pin plastic SOP 24-pin plastic SSOP (DIP-24P-M02) (FPT-24P-M01) (FPT-24P-M03) “Purchase of Fujitsu I2C components conveys a license under the Philips I2C Patent Rights to use these components in an I2C system, provided that the system conforms to the I2C Standard Specification as defined by Philips.” MB88141 (Continued) 5 V single power supply Power supply/GND for MCU interface and OP Amp is separate from power suppl...
